WROUGHT-ME TAL NUT.

Specification of Letters Patent.

Patented Nov. 24, 1908.

Application led October 30, 1907. Serial No. 399,886.

To all 'whom it may concern:

Be it known that I, FRED A. NEIDER, a citizen of the United States ofAmerica, and residentof Augusta., county of Bracken, State of Kentucky,have invented certain new and useful Improvements in lVrought- MetalNuts, of which the following is a specification.

The object of my invention is a wrought metal nut which may bemanufactured with a minimum amount of waste materia-l.

Referring to the accompanying drawings, in which I have illustratedblanks and nuts embodying` my invention, Figure l is a detail view of astrip of wrought metal from which the rolled tube is to be formed. Fig.2 and Fig. 3 are detail views of different forms of rings to be used tosurround the rolled tubes. Fig. et is a perspective view of one form ofrolled tube. Fig. 5 is a perspective view of a blank formed from arolled tube and a ring. Fig. 6 is a central sectional view of the blankshown in Fig. 5. Fig. 7 is a central sectional view of a cap nut. Fig. 8is a perspective view of a modified form of blank formed from a tube andring. Fig. 9 is a perspective view of a capped nut.

Referring to the parts: Tube, A, may be rolled either to a form circularin cross section or to one whose section form is four cornered orhexagonal. After the tube is rolled, a ring, B, whose aperturecorresponds in shape to the section of the tube, is forced down over thetube, so as to stand a short distance from one end of the tube. Thisforms the blanks shown in Figs. 5 and S, which are commercial articles.Screw threads are then cut upon the interior of tubes, A. A cap, C, maythen be placed over the end of tube, A, .and the edges of the cap may becurved under the periphery of the ring. B. A wrought metal nut is thusproduced without the loss of material.

lVha-t I claim is:

l. A nut comprising a tube of sheet metal split from end to end, andhaving screwthreads upon its interior, and a ring fitting snugly Iaroundthe tube.

2. A capped nut consisting of a splitI tube having screw-threads uponits interior, a ring fitting snugly around the tube and a cap tting overthe end of the tube and having its edges bent under the periphery of therin A capped nut consisting of a tube formed from a sheet of metal, aring surrounding the tube, and a cap formed from a disk which contactsthe end of the tube and h as its edges bent over the periphery of thering.
